The M-K X is the latest AR-15 National Match trigger from the Wisconsin trigger company. Built specifically for national match and long range competition. The M-K  X uses a national match purpose designed X disconnector. The new X disconnector has a long reset and the finest release on the market. This is very beneficial when using optics by reducing the amount of movement the shooter sees during the hammer release. Combined with the adjustable overtravel, adjustable second stage weight, multiple trigger springs, Bronze Advantage and the Wisconsin Trigger Company left or right install safety selector you have it all in one trigger.  

This is the trigger used by Madison Butler of the Texas State Rifle Association Jr. Team to set the current Junior world record in 2017 scoring a 498- 24x. Placing her as the top  woman shooter and the 1st Junior and 6th overall competitor in the nation for EIC matches in 2017.
